M235i - Stock Exhaust vs M Performance Back Box
Hey All,
I know this will have been covered, but has anyone gone from the M235i Stock exhaust to the M Sport Performance exhaust on here? I'm surprised by the sound of the stock exhaust, but worried the Performance exhaust might be too noisy in the real world. I don't want it to sound like a boy racers car!! Any thoughts? Paul |

If you're not happy with the standard noise/volume then go for it. The MPE is not really that noticeable in comfort or Eco. It's louder in sport & sport+ & on start up and you will get louder pops and crackles on downshifts. I really wouldn't describe it as noisy. If you want more volume but not too much then I would recommend it. There's some contact details on my thread where you can get a good price. http://www.2addicts.com/forums/showthread.php?t=1004397

Couldn't agree more. -Rumbles pretty good for about 45 sec on cold startup -Pops when in sport/+ w/ high rpm up/downshifts -Cruising around in Eco/Comfort it's quite civil sounding. Not annoying at all. -Does not drone when on highway. I hate when you pull up to a silly Honda Civic with a pipe and it's just blaring along. None of that here. -When you really put your foot in it, it delivers an intoxicating roar. I gotta say, if I had to do it again, I would pay double for my MPE. It dramatically improves the entire car experience, having that slightly tougher sound coming from out back. Hope you get it! |

As Bladeomatic said...
Ran with the stock for a week, which is "decent" sounding, especially in Sport mode. Put on the MPE after that week, and I note: - after startup "growl" for 20 sec or so, it quiets down. - In Comfort it is civil and not much louder than stock when cruising or light gas. - In comfort under acceleration, nice deep growl and some burbles on letting up the gas. - In Sport louder even cruising or light acceleration, however... - In Sport giving it gas, it REALLY sounds nice- deep, resonating, a low growl, and burbles nicely coming off the gas. I live in a condo with a multilevel garage, and the sound does not set off other car alarms. However I do roll down the windows and put it in Sport mode even crawling through the garage to hear that nice sound. I love this mod- makes me smile every time I give it gas, but civil and refined when not gassing. I do not note any piped in sound in either stock or MPE, as I have read in other threads. All the sound I hear is confirmed when windows are down as being outside the car. Either the sound is not piped in over the audio, or it is so subtle I can't hear it. This is one mod that I really recommend! Jonathan |
